An interesting post, @slowwalker.

I'm familiar with piled stones.

Here, in Canada, the Inuit people stack stones in such a way as to resemble a human figure.

These piled stones represent a a landmark or a commemorative sign.

It's intriguing the way patterns repeat throughout the world among people who are separated by vast distances and have no means of communication.

Perhaps, this is the best evidence of the commonality of all humanity.

Have a good day, my friend.
